Case study
Waterproofing Repairs at Westfield Bondi - Zone B Atrium
Project Overview
Westfield Bondi faced a persistent issue in Zone B of its atrium, where water leakage was damaging the common areas. The problem arose from insufficient waterproofing along a 640 lineal metre stretch, leading to water ingress seeping into the public areas below.
Challenges
Water Damage
Constant water seepage was causing visible damage, including stains and deterioration in the flooring and ceilings of the common areas.
Operational Disruption
The atrium is a high-traffic area, and repair works had to be carefully planned to minimise disruptions to shoppers and tenants.
Access and Logistics
Working in an atrium with complex architecture required special access equipment and meticulous planning.
Environmental Concerns
Ensuring that repairs were eco-friendly while addressing the water-related issues effectively.
“I was very happy to see the Atrium have the water proofing completed by the YBM team, it was a long time in planning due to the complexity of scope to get access and weather depending.
I can safely say we didn’t get any water leaks once the works were completed, professionally and in a safe manner, I have also attached a couple of photos of the boys in action earlier this year.
Highly recommend YBM. The finished product is a job well done.”

Scope of Work
Assessment and Diagnosis
Detailed inspection of the existing waterproofing system to identify failures.
Use of thermal imaging and moisture meters to pinpoint the most affected areas.
Preparation
Removal of damaged waterproofing layers.
Cleaning and surface preparation to ensure a strong bond with new materials.
Testing and Quality Assurance
Water ponding tests conducted post-application to confirm effectiveness.
Regular inspections during application to maintain quality standards.
Waterproofing Repairs
Application of a new, high-performance waterproofing membrane designed for durability.
Use of advanced sealing techniques to ensure complete coverage across 640 lineal metres.
Environmental Measures
Use of eco-friendly waterproofing materials.
Proper disposal of old materials to adhere to environmental regulations.
Execution Strategy
Staged Approach
The repairs were divided into segments to minimize disruptions and allow continuous access to parts of the atrium.
Night Works
Most repairs were conducted during off-peak hours to reduce inconvenience to shoppers and tenants.
Specialist Equipment
Elevated work platforms and scaffolding were used to access hard to reach areas.
Outcome
The waterproofing system was successfully restored, eliminating leaks and preventing further water damage.
The repairs improved the longevity of the structure and enhanced the safety and aesthetics of the atrium.
Minimal disruption to operations, with the project completed on time and within budget.
